DVB (Digital Video Broadcasting)
Digital Video Broadcasting is a set of internationally open standards for digital television. DVB standards are maintained by the DVB Project. It is an international industry consortium and is published by a Joint Technical Committee of the European Telecommunications Standards Institute, European Committee for Electrotechnical Standardization, and European Broadcasting Union.
DVB develops not only transmission protocols, but also standards for interactive applications such as digital TV set-top boxes, etc. Other DVB protocols include MHP, DVB-M, DVB-H (an “update” of the DVB-T standard for digital stream delivery to mobile devices over terrestrial networks)
DVB-C stands for Digital Video Broadcasting – Cable, “digital video broadcasting – cable”. This is a European TV standard that transmits a high-quality video stream in MPEG-2 or MPEG-4 format using a cable.
DVB-C2 is a second-generation standard with a number of advantages. It is economical, but allows you to upgrade the network, getting a clear and noise-resistant signal. The data transfer speed has increased significantly and is 83 Mbps. Which allows you to watch TV shows with virtually no interference.
DVB-S stands for “digital video broadcasting – satellite”. This is the transmission of video and audio via satellite. You will need a satellite dish to connect and set up. A very popular and still in demand in all corners of the country way to connect and watch channels.
The new DVB-S2 modulation standard is a further development of DVB-S with an improved error correction scheme. Thus, the amount of data transmitted through the transponder can be increased by 40%. When transmitting HDTV in 720p format with MPEG-4 AVC or VC1 encoding at 8 Mbps per program. The number of programs transmitted through the transponder can reach six.
DVB-T stands for “digital video broadcasting – terrestrial”. This is the transmission of video and audio using terrestrial television networks. In the house connect a conventional indoor antenna to a decoder to receive such a signal. Error correction is a key tool for achieving the best performance of a satellite data link in a high noise and interference environment. The DVB-T standard is a standard for terrestrial television broadcasting.
The second generation of the DVB-T standard significantly increases throughput. It also allows you to transfer video in UHD and 3D format.
DVB-H (Digital Video Broadcasting – Handheld, portable digital video broadcasting) is a mobile television standard that allows you to transmit digital video signals to mobile devices (PDA, mobile phone, portable TV, etc.) Developed by the Finnish company Nokia, adopted in November 2004
